TD-LTE antenna deployment scenario analysis
Since 2013, the global TD-LTE network has entered a period of vigorous development. According to the latest statistics, as of May 2013, 17 TD-LTE networks have been commercialized worldwide, and more than 40 operators have announced a clear TD-LTE commercial plan. The number of global TD-LTE users has exceeded 3 million. However, since the current TD-LTE network deployment is mainly concentrated in the F-band (1880-1920MHz) and D-band (2500-2690MHz), or upgraded from the original TD-SCDMA network, how to choose the appropriate for different site-building scenarios Antennas, while ensuring optimal network performance, are a major challenge for operators. This paper hopes to provide some ideas for operators to solve the above challenges by analyzing different network scenarios and combining the different performances of the antennas.
At present, the main TD-LTE antennas are FA/D dual-frequency independent electrical adjustment antennas and FAD broadband antennas. Among them, the FA/D dual-frequency independent electrical adjustment antenna is mainly applicable to the scenes of the FA band (F band: 1880~1920MHz, A band: 2010~2025MHz) and D band (2500~2690MHz). The FAD wideband antenna supports any frequency band in the entire FAD band, and is suitable for scenarios where the sky space is sufficient, the FA band and the D band are independently deployed.
The following table will analyze the antenna deployment for two typical scenarios:
Bright White Candles/velas/bougies .make of paraffin wax ,and stearic acid .
snow white and pure white color ,very bright quality holy brand candles .happy candles .OEM brand .
usually yellow color box packing ,red color box packing this packing more popular aslo the box can add shrink paper pack ,and 35g/pc 8x30box/ctn 36g /pc /
if any inquire pls tell me exact weight ,then I will offer you best price .welcome to visit my factory
and shipment in the 30days after get the depsoit .
